When I was getting my Ph.D. in Computer Science, I had to take an oral exam where I was told to prove a mathematical theorem.  It was not the most natural task for me.  We look at the story of David and Goliath - and how a determined, faithful man was able to do something that must have surprised many of those around him.  We consider how putting full trust in God can enable us to do things we might otherwise not be able to do - and how it can empower us to find the life that God truly wants us to live.
